2. How Does a Hydraulic Rock Breaker Work?
The core function of a hydraulic rock breaker involves converting hydraulic power into mechanical force to fracture hard materials. This process consists of several key stages.
2.1. Hydraulic System Basics
The hydraulic system is the heart of the rock breaker, utilizing hydraulic oil to transmit power. The system typically includes:
- Hydraulic Pump: Generates high-pressure oil flow.
- Control Valve: Regulates the flow of hydraulic oil to the piston.
- Hydraulic Cylinder: Contains the piston that drives the impact tool.
- Hydraulic Accumulator: Stores hydraulic energy for increased impact force.
2.2. The Piston Mechanism
The piston is a critical component that translates hydraulic energy into mechanical force. The process involves:
- Piston Activation: High-pressure oil enters the hydraulic cylinder, driving the piston upwards.
- Energy Storage: As the piston moves, it compresses nitrogen gas in the accumulator.
- Impact Generation: When the exhaust valve opens, the stored energy is released, forcing the piston downwards with significant force.
- Material Fracture: The piston strikes the tool, delivering a powerful impact that fractures the material.
This cycle repeats rapidly, allowing the hydraulic breaker to efficiently break through hard surfaces.
2.3. Step-by-Step Operation
Here’s a detailed breakdown of how a hydraulic breaker operates:
- Initialization: The piston starts at the bottom dead center, allowing the mandrel to move freely.
- Upward Stroke: High-pressure oil acts on the lower working surface of the piston head, raising the striking piston.
- Compression: As the piston moves upwards, it closes the outlet gap and compresses nitrogen gas in the accumulator.
- Downward Stroke: The exhaust valve opens, releasing the compressed energy and pushing the piston downwards.
- Impact: The piston strikes the tool with great force, breaking the material.
- Repetition: The cycle repeats continuously for efficient demolition or rock breaking.
2.4. Key Components and Their Functions
- Cylinder & Valves: Precision finishing treatment prevents scuffing.
- Piston: Machined to perfect tolerance according to each cylinder.
